The Sandusky is a two-masted brig built in 1848 that sank in a gale in September 1856. Her hull sits intact and tipped slightly to port in 26 m (85 ft) of water five miles west of the Mackinac Bridge, with a topmast, windlass and bilge pumps still in place and a replica scroll figurehead under the jib-boom.

The dive

The preserve mooring sits about 6 m (20 ft) off the port side aft, and a small line guides divers from it to the rail, so the first contact with the ship is the after port rail. The brig lies between 21 m (70 ft) and 26 m (85 ft), five miles west of the bridge, her hull intact and tipped slightly to port, with a number of artifacts on and around the wreck.

Along the deck the centerboard winch, bilge pumps and windlass all remain, and a topmast reaches from the port rail down to the bottom. At the bow a scroll figurehead sits below the intact jib-boom; it is a replica, and the original, recovered with State permission, is in the Straits Shipwreck Museum at Old Mackinac Point Light in Mackinaw City. The decks are collapsing in places and the brig shows severe wear, so the preserve asks divers not to touch or disturb any artifacts.

Built in 1848 in Sandusky, Ohio, the brig Sandusky is the oldest known shipwreck in the preserve that divers visit. She was bound from Chicago to Buffalo with a load of grain in September 1856 when a violent gale sprang up on the northern end of Lake Michigan and caught her in the Straits.
